Definitions

  • the invention relates to a quick connection arrangement for the detachable connection of a media line with a (SAE) nozzle.

  • Such a quick connector assembly according to the preamble of claim 1 is known from EP 0 663 557 A known. It has long been known to perform the connection between media-conveying lines and connections by means of quick connections or quick couplings, so-called. Quick Connectors (QC), to save time during assembly.
  • QC Quick Connectors
  • These quick connections are used, for example, for device connections that are designed as sockets according to SAE-J 2044.
  • Such quick connections are often used in the automotive industry, for example in the low-pressure area of fluid-conveying lines, ie at fluid pressures of up to about 10 bar, at various interfaces, for example on the tank or in pumps, filters, valves, etc.
  • a disadvantage of the known such quick connections that it is not recognizable in the used quick connections, whether the male part (SAE connector) is properly locked. If the locking of the quick connection is not done properly, this can dissolve during operation, ie the fluid-carrying line dissolves uncontrolled from the nozzle and the fluid occurs solid in eg the engine compartment of the vehicle. Especially with fuel lines, this can be very dangerous for the user of the vehicle, as a result, a vehicle fire can be caused by leaking fuel.
  • the object of the present invention is to provide a quick connector assembly of the type described above, in which a quick and easy connection of the media line and nozzle is made possible and at the same time optically or tactile easily and reliably recognize that the quick connection properly and securely locked is.
  • the object is achieved by the features of claim 1. Advantageous developments are described in the subclaims.
  • the present invention is based on the finding that the successful latching or locking between the nozzle and the media line can be visually or visually and tactually indicated by the fact that the complete locking of the quick connector assembly is effected by the outer locking element and this locking state recognizable from the non-locking conclusive or not perfect lock state of the quick connector assembly recognizably different.
  • This finding is implemented according to the invention in that an inner locking element firstly locks the connection piece in the connection opening of the housing of the quick connection arrangement and this is in turn locked from the outside by an outer locking element.
  • this second locking step From the outside easy and secure visually and possibly also additionally tactile recognizable, so that a secure and fast connection is created, the successful, safe and reliable installation can be easily, quickly and safely checked from the outside.
  • these two locking steps and thus the quick connection can be canceled again easily, quickly and non-destructive.
  • both the nozzle and the quick connector assembly according to the invention can be reused according to the invention.
  • the housing and the inner and outer locking element may comprise or consist of a plastic.
  • a plastic it is preferable to use a polyamide (PA), polyphthalamide (PPA) or polyphenylene sulfide (PPS). It is particularly preferred to use as the material of the housing PA12, PA612, PA610, PPA or PPS, as the material of the inner locking element PA11, PA612 or PA610 and as the material of the outer locking element PA12, PA612, PA610.

  • the outer locking member has at least one locking arm cover which, in a first position, can release the locking arm recess and, in a second position, block the locking arm recess.
  • the advantage here is that can be created by radially-arranged Kohlbare from the housing locking arms of the inner locking element, a simple locking mechanism for locking a collar of the neck. At the same time can be done by preventing the pushing out of the locking arms by the outer blockage by means of Verriegelungsarmabdeckung the outer locking element a simple backup of the latched nozzle, which is also both optically and tactile easy and safe recognizable by the required change in position of the outer locking element.
  • the outer locking element between the first position and the second position can be moved substantially in the direction of the longitudinal axis A of the quick connector assembly.
  • longitudinal movement is quick and easy to perform.
  • a change in position of the outer locking element in the longitudinal direction is easily and securely recognizable both optically and tactually.
  • the outer locking element can be kept positioned relative to the housing both in the first position and in the second position. It is advantageous in this case that both positions can be taken defined by this, for example by locking the outer locking element on the housing in the two positions.
  • the inner locking member has at least one release mechanism which places the outer locking member in a movable condition from a substantially immovable condition in the direction of the longitudinal axis A when the (SAE) port is inserted into the port opening.
  • the housing has at least one recess through which the release mechanism of the inner locking member can release a locking mechanism of the outer locking member when the (SAE) port is inserted into the port opening.
  • the advantage here is that by the blocking mechanism, the outer locking element can be securely held in its (first) position and the release for movement in the direction of the longitudinal axis A during insertion of the nozzle takes place automatically. This simplifies and speeds up assembly.
  • the advantage here is that the unlocking of the outer locking element can be done in this way that the opening ring is pressed radially inward, eg manually, and by this radial constriction in this area the region of the opening ring in which, for example, the blocking mechanism or the locking arms of the outer locking member are radially expanded such that thereby the cams of the locking arms are released radially from the corresponding opening recesses of the housing, whereby the blockage of the outer locking member in the (second) position in which the outer locking member secures the inner locking element , can be solved.
